Not sure if these will be of any interest to anyone on here...but as I'm not on retrobike i'll give it a shot. :]
I have a pair of completely unused Panaracer Timbuk 2 tyres for sale. 26" of course. Brand new re-issues made from the original molds but with folding beads.
They're almost a hundred dollars a pair, plus shipping, and import...so I'm looking for £5O the pair, posted.
Perfect for that retro project you've been putting off all winter! :]
